(In reply to Liu Shukui from comment #7) > the reproducer cannot be compiled on sle15sp1. Right. 32-bit GStremaer development is quite broken (what with gstreamer-devel-32bit being missing) but it seems to be making progress. In the meantime here is how to compile it: zypper install gcc-32bit glibc-devel-32bit gstreamer-devel zypper install glib2-devel glib2-devel-32bit zypper install gstreamer-plugins-base-devel gstreamer-plugins-base-devel-32bit ln -s /usr/lib/libgstbase-1.0.so.0 /usr/lib/libgstbase-1.0.so ln -s /usr/lib/libgstreamer-1.0.so.0 /usr/lib/libgstreamer-1.0.so # one line gcc -m32 -o checkgst32 `pkg-config --cflags gstreamer-1.0` `pkg-config --libs gstreamer-1.0` checkgst.c
